How can i get admission in LLB three years...??please tell.

Dear Rabbani, University of Luckmow doesnt have a 3 year LLB course. It has a 5 year LLB course whose eligibility criteria is that you should have completed your 10+2 with a minimum aggregate of 45%. It is 45% for General Category and 40% for Reserved Categories. The admission is based on an entrance examination for 100 marks to be answered in 90 minutes. The online applications will be available at their official website.

Hello Rabbani,
3-year LLB course is for students who have completed their graduation from any stream.
Some top law schools, including faculties like Faculty of Law, DU and Faculty of Law, Banaras Hindu University (BHU) offer the three-year LLB course.
Different Entrance exams for which you can appear in order to get admission for this course are,
University of Delhi (DU) LLB Entrance Test
BHU  UET (Law)
LSAT-India
LAWCET of Andhra Pradesh
IIT Kharagpur (Own Test & LSAT-India)
And admissions will be conducted based on merit of these exams.
There is no upper age-limit for admission. However a candidate must be at least 17 years of age on the date of application. A graduation degree with 45% marks (40% for reserved category) is the basic qualification required. Universities like DU and BHU require minimum 50% marks while universities like Kurukshetra, Rohtak, Meerut require only 45% marks in graduation.
